Hazardous Waste Information Management System

The Michigan Department of Environmental Quality (MDEQ) Resource Management Division (RMD) contracted Windsor to perform a multi-phased project for the development of an integrated cross-program waste management system.  Prior to this project the Division maintained nine separate internal information systems in addition to staff having to hand-key data into EPA’s Resource Conservation and Recovery Act Information (RCRAInfo) system for the management of hazardous waste information.  The first version of the MDEQ’s Waste Data System was delivered by Windsor Solutions for production use in 2001.

In 2009 the MDEQ contracted with Windsor Solutions to redevelop the Waste Data System in current technologies.  In the intervening period between initial production release and 2009, both web and database technologies had advanced significantly as to warrant the investment of resources for an application that was so critical to the day to day work processes of the Division. 

The current implementation of the Waste Data System is a web based application based on the Microsoft .NET Framework with data being managed and reported upon using the Microsoft’s SQL Server platform and its associated services (Reporting Services, Integration Services).  The application is available both internally and publicly ( with sensitive data being removed from the publicly available version. The division has found that making the data publicly available has resulted in a significant decrease in the number of information requests submitted by the public, freeing up resource-limited staff to address other pressing matters. 

Programmatically, the Waste Data System manages data for the following areas:

  • RCRA Hazardous Waste Generation and Management
  • RCRA Hazardous Waste Manifesting
  • Hazardous Waste and Liquid Industrial Waste Transporters
  • Solid Waste Management
  • Scrap Tires

Data for both the Site Identification and the Compliance Monitoring and Enforcement activities are managed in a cross-programmatic manner.  This allows staff and the public to have an integrated view of the regulated activities and compliance history at a site. The Waste Data System also has implemented a proven approach to submitting data through the Exchange Network to EPA’s Central Data Exchange (CDX) for incorporation into RCRAInfo.  Each of the corresponding modules within the Waste Data System was designed with this objective in mind and the MDEQ has been successfully translating data to RCRAInfo since 2001 (originally flat files).
